In typescript, the declaration is something like this:
const regex : RegExp = /.+\*.+/;
using RegExp constructor:
const regex = new RegExp('.+\\*.+');
It is how to save results to CSV on the client-side without additional non-standard tools.
This example uses only mysql
client and awk
.
One-line:
mysql --skip-column-names --batch -e 'select * from dump3' t | awk -F'\t' '{ sep=""; for(i = 1; i <= NF; i++) { gsub(/\\t/,"\t",$i); gsub(/\\n/,"\n",$i); gsub(/\\\\/,"\\",$i); gsub(/"/,"\"\"",$i); printf sep"\""$i"\""; sep=","; if(i==NF){printf"\n"}}}'
Logical explanation of what is needed to do
First, let see how data looks like in RAW mode (with --raw
option). the database and table are respectively t
and dump3
You can see the field starting from "new line" (in the first row) is splitted into three lines due to new lines placed in the value.
mysql --skip-column-names --batch --raw -e 'select * from dump3' t one line 2 new line quotation marks " backslash \ two quotation marks "" two backslashes \\ two tabs new line the end of field another line 1 another line description without any special chars
--raw
option) - each record changed to the one-line texts by escaping characters like \
<tab>
and new-lines
mysql --skip-column-names --batch -e 'select * from dump3' t one line 2 new line\nquotation marks " backslash \\ two quotation marks "" two backslashes \\\\ two tabs\t\tnew line\nthe end of field another line 1 another line description without any special chars
The clue is to save data in CSV format with escaped characters.
The way to do that is to convert special entities which mysql --batch
produces (\t
as tabs \\
as backshlash and \n
as newline) into equivalent bytes for each value (field).
Then whole value is escaped by "
and enclosed also by "
.
Btw - using the same characters for escaping and enclosing gently simplifies output and processing, because you don't have two special characters.
For this reason all you have to do with values (from csv format perspective) is to change "
to ""
whithin values. In more common way (with escaping and enclosing respectively \
and "
) you would have to first change \
to \\
and then change "
into \"
.
And the commands' explanation step by step:
# we produce one-line output as showed in step 2. mysql --skip-column-names --batch -e 'select * from dump3' t # set fields separator to because mysql produces in that way | awk -F'\t' # this start iterating every line/record from the mysql data - standard behaviour of awk '{ # field separator is empty because we don't print a separator before the first output field sep=""; -- iterating by every field and converting the field to csv proper value for(i = 1; i <= NF; i++) { -- note: \\ two shlashes below mean \ for awk because they're escaped -- changing \t into byte corresponding to <tab> gsub(/\\t/, "\t",$i); -- changing \n into byte corresponding to new line gsub(/\\n/, "\n",$i); -- changing two \\ into one \ gsub(/\\\\/,"\\",$i); -- changing value into CSV proper one literally - change " into "" gsub(/"/, "\"\"",$i); -- print output field enclosed by " and adding separator before printf sep"\""$i"\""; -- separator is set after first field is processed - because earlier we don't need it sep=","; -- adding new line after the last field processed - so this indicates csv record separator if(i==NF) {printf"\n"} } }'
I don't get that part about the string stuff, but why don't you use the modulo operator (%
) to check if a number is dividable by another? If a number is dividable by another, the other is automatically a multiple of that number.
It goes like that:
int a = 10; int b = 5;
// is a a multiple of b
if ( a % b == 0 ) ....
An object file is just what you get when you compile one (or several) source file(s).
It can be either a fully completed executable or library, or intermediate files.
The object files typically contain native code, linker information, debugging symbols and so forth.
Try using
Dir.glob(".")
To see what's in the directory (and therefore what directory it's looking at).
Intent takePhoto = new Intent("android.media.action.IMAGE_CAPTURE");
startActivityForResult(takePhoto, CAMERA_PIC_REQUEST)
and set
CAMERA_PIC_REQUEST= 1 or 0
In case you want to remove elements which are added dynamically try this:
document.body.addEventListener('DOMSubtreeModified', function(event) {
const elements = document.getElementsByClassName('your-class-name');
while (elements.length > 0) elements[0].remove();
});
Do it with CSS3-Transitions. Support is great (all modern browsers, even IE). With Compass and SASS this is quickly done:
#foo {background:red; @include transition(background 1s)}
#foo:hover {background:yellow}
Pure CSS:
#foo {
background:red;
-webkit-transition:background 1s;
-moz-transition:background 1s;
-o-transition:background 1s;
transition:background 1s
}
#foo:hover {background:yellow}
I've wrote an german article about this topic: http://www.solife.cc/blog/animation-farben-css3-transition.html

Note if you want add view in Full screen then only use below code
Add these extension of UIViewController
public extension UIViewController {
internal func makeViewAsFullScreen() {
var viewFrame:CGRect = self.view.frame
if viewFrame.origin.y > 0 || viewFrame.origin.x > 0 {
self.view.frame = UIScreen.main.bounds
}
}
}
Continue as normal adding process of subview
Now use in adding UIViewController's viewDidAppear
override func viewDidAppear(_ animated: Bool) {
super.viewDidAppear(animated)
self.makeViewAsFullScreen()
}
A code like that should work:
int i = 0;
char string[256], c;
while(i < 256 - 1 && (c = fgetc(fp) != EOF)) //Keep space for the final \0
{
string[i++] = c;
}
string[i] = '\0';
that the OpenSSL extension enabled and the directory languages with "br"? first checks the data.
.container {overflow:auto;} will do the trick. If you want to control specific direction, you should set auto for that specific axis. A.E.
.container {overflow-y:auto;} .container {overflow-x:hidden;}
The above code will hide any overflow in the x-axis and generate a scroll-bar when needed on the y-axis.But you have to make sure that you content default height smaller than the container height; if not, the scroll-bar will not be hidden.

I think you have two alternatives. For dom elements such as jQuery and like frameworks give you a good method of iteration. The second approach is the for loop.
let phone = "tel://\("1234567890")";
let url:NSURL = NSURL(string:phone)!;
UIApplication.sharedApplication().openURL(url);
Strangely enough,
package main
func main () {
var sessions = map[string] chan int{};
delete(sessions, "moo");
}
seems to work. This seems a poor use of resources though!
Another way is to check for existence and use the value itself:
package main
func main () {
var sessions = map[string] chan int{};
sessions["moo"] = make (chan int);
_, ok := sessions["moo"];
if ok {
delete(sessions, "moo");
}
}
This my version, maybe usefull for others, using String builder Saw that someone had the same piece of code.
public String FormatXml(String xml, String tab)
{
var sb = new StringBuilder();
int indent = 0;
// find all elements
foreach (string node in Regex.Split(xml,@">\s*<"))
{
// if at end, lower indent
if (Regex.IsMatch(node, @"^\/\w")) indent--;
sb.AppendLine(String.Format("{0}<{1}>", string.Concat(Enumerable.Repeat(tab, indent).ToArray()), node));
// if at start, increase indent
if (Regex.IsMatch(node, @"^<?\w[^>]*[^\/]$")) indent++;
}
// correct first < and last > from the output
String result = sb.ToString().Substring(1);
return result.Remove(result.Length - Environment.NewLine.Length-1);
}
I know this is an older question, but for reference, a really simple way for formatting dates without any data annotations or any other settings is as follows:
@Html.TextBoxFor(m => m.StartDate, new { @Value = Model.StartDate.ToString("dd-MMM-yyyy") })
The above format can of course be changed to whatever.
Yes: replace_all
is one of the boost string algorithms:
Although it's not a standard library, it has a few things on the standard library:
replace_all
nested inside a trim
). That's a bit more involved for the standard library functions.I have this sample Java Code:
import java.io.*;
import java.net.*;
import java.nio.charset.StandardCharsets;
public class TestClass {
public static void main(String[] args) throws IOException {
ServerSocket socket = new ServerSocket(8081);
Socket accept = socket.accept();
InputStream inputStream = accept.getInputStream();
InputStreamReader inputStreamReader = new InputStreamReader(inputStream, StandardCharsets.UTF_8);
char readChar;
while ((readChar = (char) inputStreamReader.read()) != -1) {
System.out.print(readChar);
}
inputStream.close();
accept.close();
System.exit(1);
}
}
and I have this test.html file:
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>File Upload!</title>
</head>
<body>
<form method="post" action="http://localhost:8081" enctype="multipart/form-data">
<input type="file" name="file" id="file">
<input type="submit">
</form>
</body>
</html>
and finally the file I will be using for testing purposes, named a.dat has the following content:
0x39 0x69 0x65
if you interpret the bytes above as ASCII or UTF-8 characters, they will actually will be representing:
9ie
So let 's run our Java Code, open up test.html in our favorite browser, upload a.dat
and submit the form and see what our server receives:

I got this error Unexpected identifier
because of a missing semi-colon ;
at the end of a line. Anyone wandering here for other than above-mentioned solutions, This might also be the cause of this error.
Let's say I have 32-bit ARGB value with 8-bits per channel. I want to replace the alpha component with another alpha value, such as 0x45
unsigned long alpha = 0x45
unsigned long pixel = 0x12345678;
pixel = ((pixel & 0x00FFFFFF) | (alpha << 24));
The mask turns the top 8 bits to 0, where the old alpha value was. The alpha value is shifted up to the final bit positions it will take, then it is OR-ed into the masked pixel value. The final result is 0x45345678 which is stored into pixel.
For substracting in moment.js:
moment().subtract(1, 'months').format('MMM YYYY');
Documentation:
http://momentjs.com/docs/#/manipulating/subtract/
Before version 2.8.0, the moment#subtract(String, Number) syntax was also supported. It has been deprecated in favor of moment#subtract(Number, String).
moment().subtract('seconds', 1); // Deprecated in 2.8.0
moment().subtract(1, 'seconds');
As of 2.12.0 when decimal values are passed for days and months, they are rounded to the nearest integer. Weeks, quarters, and years are converted to days or months, and then rounded to the nearest integer.
moment().subtract(1.5, 'months') == moment().subtract(2, 'months')
moment().subtract(.7, 'years') == moment().subtract(8, 'months') //.7*12 = 8.4, rounded to 8
listview.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, final View view, int position, long id) {
View v;
int count = parent.getChildCount();
v = parent.getChildAt(position);
parent.requestChildFocus(v, view);
v.setBackground(res.getDrawable(R.drawable.transparent_button));
for (int i = 0; i < count; i++) {
if (i != position) {
v = parent.getChildAt(i);
v.setBackground(res.getDrawable(R.drawable.not_clicked));
}
}
}
});
Basically, create two Drawables - one that is transparent, and another that is the desired color. Request focus at the clicked position (int position
as defined) and change the color of the said row. Then walk through the parent ListView
, and change all other rows accordingly. This accounts for when a user clicks on the listview
multiple times. This is done with a custom layout for each row in the ListView
. (Very simple, just create a new layout file with a TextView
- do not set focusable or clickable!).
No custom adapter required - use ArrayAdapter

The %c
conversion specifier won't automatically skip any leading whitespace, so if there's a stray newline in the input stream (from a previous entry, for example) the scanf
call will consume it immediately.
One way around the problem is to put a blank space before the conversion specifier in the format string:
scanf(" %c", &c);
The blank in the format string tells scanf
to skip leading whitespace, and the first non-whitespace character will be read with the %c
conversion specifier.
I solved this problem by adding a variable in the token data:
softexp - I set this to 5 mins (300 seconds)
I set expiresIn
option to my desired time before the user will be forced to login again. Mine is set to 30 minutes. This must be greater than the value of softexp
.
When my client side app sends request to the server API (where token is required, eg. customer list page), the server checks whether the token submitted is still valid or not based on its original expiration (expiresIn
) value. If it's not valid, server will respond with a status particular for this error, eg. INVALID_TOKEN
.
If the token is still valid based on expiredIn
value, but it already exceeded the softexp
value, the server will respond with a separate status for this error, eg. EXPIRED_TOKEN
:
(Math.floor(Date.now() / 1000) > decoded.softexp)
On the client side, if it received EXPIRED_TOKEN
response, it should renew the token automatically by sending a renewal request to the server. This is transparent to the user and automatically being taken care of the client app.
The renewal method in the server must check if the token is still valid:
jwt.verify(token, secret, (err, decoded) => {})
The server will refuse to renew tokens if it failed the above method.
In iTunes 11 you can go to the view menu, and "Show Sidebar", this will give you the sidebar, that you can drag 'n drop to.
You'll drag 'n drop to the open area that will be near the bottom of the sidebar (I'm typically doing this with both an IPA and a provisioning profile). After you do that, there will be an apps menu that appears in the sidebar with your app in it. Click on that, and you'll see your application in the main view. You can then drag your application from there to your device.

Quick answer:
A child scope normally prototypically inherits from its parent scope, but not always. One exception to this rule is a directive with scope: { ... }
-- this creates an "isolate" scope that does not prototypically inherit. This construct is often used when creating a "reusable component" directive.
As for the nuances, scope inheritance is normally straightfoward... until you need 2-way data binding (i.e., form elements, ng-model) in the child scope. Ng-repeat, ng-switch, and ng-include can trip you up if you try to bind to a primitive (e.g., number, string, boolean) in the parent scope from inside the child scope. It doesn't work the way most people expect it should work. The child scope gets its own property that hides/shadows the parent property of the same name. Your workarounds are
New AngularJS developers often do not realize that ng-repeat
, ng-switch
, ng-view
, ng-include
and ng-if
all create new child scopes, so the problem often shows up when these directives are involved. (See this example for a quick illustration of the problem.)
This issue with primitives can be easily avoided by following the "best practice" of always have a '.' in your ng-models – watch 3 minutes worth. Misko demonstrates the primitive binding issue with ng-switch
.
Having a '.' in your models will ensure that prototypal inheritance is in play. So, use
<input type="text" ng-model="someObj.prop1">
<!--rather than
<input type="text" ng-model="prop1">`
-->
Also placed on the AngularJS wiki: https://github.com/angular/angular.js/wiki/Understanding-Scopes
It is important to first have a solid understanding of prototypal inheritance, especially if you are coming from a server-side background and you are more familiar with class-ical inheritance. So let's review that first.
Suppose parentScope has properties aString, aNumber, anArray, anObject, and aFunction. If childScope prototypically inherits from parentScope, we have:
(Note that to save space, I show the anArray
object as a single blue object with its three values, rather than an single blue object with three separate gray literals.)
If we try to access a property defined on the parentScope from the child scope, JavaScript will first look in the child scope, not find the property, then look in the inherited scope, and find the property. (If it didn't find the property in the parentScope, it would continue up the prototype chain... all the way up to the root scope). So, these are all true:
childScope.aString === 'parent string'
childScope.anArray[1] === 20
childScope.anObject.property1 === 'parent prop1'
childScope.aFunction() === 'parent output'
Suppose we then do this:
childScope.aString = 'child string'
The prototype chain is not consulted, and a new aString property is added to the childScope. This new property hides/shadows the parentScope property with the same name. This will become very important when we discuss ng-repeat and ng-include below.
Suppose we then do this:
childScope.anArray[1] = '22'
childScope.anObject.property1 = 'child prop1'
The prototype chain is consulted because the objects (anArray and anObject) are not found in the childScope. The objects are found in the parentScope, and the property values are updated on the original objects. No new properties are added to the childScope; no new objects are created. (Note that in JavaScript arrays and functions are also objects.)
Suppose we then do this:
childScope.anArray = [100, 555]
childScope.anObject = { name: 'Mark', country: 'USA' }
The prototype chain is not consulted, and child scope gets two new object properties that hide/shadow the parentScope object properties with the same names.
Takeaways:
One last scenario:
delete childScope.anArray
childScope.anArray[1] === 22 // true
We deleted the childScope property first, then when we try to access the property again, the prototype chain is consulted.
The contenders:
scope: true
, directive with transclude: true
.scope: { ... }
. This creates an "isolate" scope instead.Note, by default, directives do not create new scope -- i.e., the default is scope: false
.
Suppose we have in our controller:
$scope.myPrimitive = 50;
$scope.myObject = {aNumber: 11};
And in our HTML:
<script type="text/ng-template" id="/tpl1.html">
<input ng-model="myPrimitive">
</script>
<div ng-include src="'/tpl1.html'"></div>
<script type="text/ng-template" id="/tpl2.html">
<input ng-model="myObject.aNumber">
</script>
<div ng-include src="'/tpl2.html'"></div>
Each ng-include generates a new child scope, which prototypically inherits from the parent scope.
Typing (say, "77") into the first input textbox causes the child scope to get a new myPrimitive
scope property that hides/shadows the parent scope property of the same name. This is probably not what you want/expect.
Typing (say, "99") into the second input textbox does not result in a new child property. Because tpl2.html binds the model to an object property, prototypal inheritance kicks in when the ngModel looks for object myObject -- it finds it in the parent scope.
We can rewrite the first template to use $parent, if we don't want to change our model from a primitive to an object:
<input ng-model="$parent.myPrimitive">
Typing (say, "22") into this input textbox does not result in a new child property. The model is now bound to a property of the parent scope (because $parent is a child scope property that references the parent scope).
For all scopes (prototypal or not), Angular always tracks a parent-child relationship (i.e., a hierarchy), via scope properties $parent, $$childHead and $$childTail. I normally don't show these scope properties in the diagrams.
For scenarios where form elements are not involved, another solution is to define a function on the parent scope to modify the primitive. Then ensure the child always calls this function, which will be available to the child scope due to prototypal inheritance. E.g.,
// in the parent scope
$scope.setMyPrimitive = function(value) {
$scope.myPrimitive = value;
}
Here is a sample fiddle that uses this "parent function" approach. (The fiddle was written as part of this answer: https://stackoverflow.com/a/14104318/215945.)
See also https://stackoverflow.com/a/13782671/215945 and https://github.com/angular/angular.js/issues/1267.
ng-switch scope inheritance works just like ng-include. So if you need 2-way data binding to a primitive in the parent scope, use $parent, or change the model to be an object and then bind to a property of that object. This will avoid child scope hiding/shadowing of parent scope properties.
See also AngularJS, bind scope of a switch-case?
Ng-repeat works a little differently. Suppose we have in our controller:
$scope.myArrayOfPrimitives = [ 11, 22 ];
$scope.myArrayOfObjects = [{num: 101}, {num: 202}]
And in our HTML:
<ul><li ng-repeat="num in myArrayOfPrimitives">
<input ng-model="num">
</li>
<ul>
<ul><li ng-repeat="obj in myArrayOfObjects">
<input ng-model="obj.num">
</li>
<ul>
For each item/iteration, ng-repeat creates a new scope, which prototypically inherits from the parent scope, but it also assigns the item's value to a new property on the new child scope. (The name of the new property is the loop variable's name.) Here's what the Angular source code for ng-repeat actually is:
childScope = scope.$new(); // child scope prototypically inherits from parent scope
...
childScope[valueIdent] = value; // creates a new childScope property
If item is a primitive (as in myArrayOfPrimitives), essentially a copy of the value is assigned to the new child scope property. Changing the child scope property's value (i.e., using ng-model, hence child scope num
) does not change the array the parent scope references. So in the first ng-repeat above, each child scope gets a num
property that is independent of the myArrayOfPrimitives array:
This ng-repeat will not work (like you want/expect it to). Typing into the textboxes changes the values in the gray boxes, which are only visible in the child scopes. What we want is for the inputs to affect the myArrayOfPrimitives array, not a child scope primitive property. To accomplish this, we need to change the model to be an array of objects.
So, if item is an object, a reference to the original object (not a copy) is assigned to the new child scope property. Changing the child scope property's value (i.e., using ng-model, hence obj.num
) does change the object the parent scope references. So in the second ng-repeat above, we have:
(I colored one line gray just so that it is clear where it is going.)
This works as expected. Typing into the textboxes changes the values in the gray boxes, which are visible to both the child and parent scopes.
See also Difficulty with ng-model, ng-repeat, and inputs and https://stackoverflow.com/a/13782671/215945
Nesting controllers using ng-controller results in normal prototypal inheritance, just like ng-include and ng-switch, so the same techniques apply. However, "it is considered bad form for two controllers to share information via $scope inheritance" -- http://onehungrymind.com/angularjs-sticky-notes-pt-1-architecture/ A service should be used to share data between controllers instead.
(If you really want to share data via controllers scope inheritance, there is nothing you need to do. The child scope will have access to all of the parent scope properties. See also Controller load order differs when loading or navigating)
scope: false
) - the directive does not create a new scope, so there is no inheritance here. This is easy, but also dangerous because, e.g., a directive might think it is creating a new property on the scope, when in fact it is clobbering an existing property. This is not a good choice for writing directives that are intended as reusable components.scope: true
- the directive creates a new child scope that prototypically inherits from the parent scope. If more than one directive (on the same DOM element) requests a new scope, only one new child scope is created. Since we have "normal" prototypal inheritance, this is like ng-include and ng-switch, so be wary of 2-way data binding to parent scope primitives, and child scope hiding/shadowing of parent scope properties.scope: { ... }
- the directive creates a new isolate/isolated scope. It does not prototypically inherit. This is usually your best choice when creating reusable components, since the directive cannot accidentally read or modify the parent scope. However, such directives often need access to a few parent scope properties. The object hash is used to set up two-way binding (using '=') or one-way binding (using '@') between the parent scope and the isolate scope. There is also '&' to bind to parent scope expressions. So, these all create local scope properties that are derived from the parent scope.
Note that attributes are used to help set up the binding -- you can't just reference parent scope property names in the object hash, you have to use an attribute. E.g., this won't work if you want to bind to parent property parentProp
in the isolated scope: <div my-directive>
and scope: { localProp: '@parentProp' }
. An attribute must be used to specify each parent property that the directive wants to bind to: <div my-directive the-Parent-Prop=parentProp>
and scope: { localProp: '@theParentProp' }
.
__proto__
references Object.
Isolate scope's $parent references the parent scope, so although it is isolated and doesn't inherit prototypically from the parent scope, it is still a child scope.
<my-directive interpolated="{{parentProp1}}" twowayBinding="parentProp2">
and
scope: { interpolatedProp: '@interpolated', twowayBindingProp: '=twowayBinding' }
scope.someIsolateProp = "I'm isolated"
transclude: true
- the directive creates a new "transcluded" child scope, which prototypically inherits from the parent scope. The transcluded and the isolated scope (if any) are siblings -- the $parent property of each scope references the same parent scope. When a transcluded and an isolate scope both exist, isolate scope property $$nextSibling will reference the transcluded scope. I'm not aware of any nuances with the transcluded scope.
transclude: true
This fiddle has a showScope()
function that can be used to examine an isolate and transcluded scope. See the instructions in the comments in the fiddle.
There are four types of scopes:
scope: true
scope: {...}
. This one is not prototypal, but '=', '@', and '&' provide a mechanism to access parent scope properties, via attributes.transclude: true
. This one is also normal prototypal scope inheritance, but it is also a sibling of any isolate scope.For all scopes (prototypal or not), Angular always tracks a parent-child relationship (i.e., a hierarchy), via properties $parent and $$childHead and $$childTail.
Diagrams were generated with graphviz "*.dot" files, which are on github. Tim Caswell's "Learning JavaScript with Object Graphs" was the inspiration for using GraphViz for the diagrams.
Borrowing directly from Gordon's very comprehensive answer, I note that your question mentions being page-specific in forcing HTTPS/SSL connections.
function forceHTTPS(){
$httpsURL = 'https://'.$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI'];
if( count( $_POST )>0 )
die( 'Page should be accessed with HTTPS, but a POST Submission has been sent here. Adjust the form to point to '.$httpsURL );
if( !isset( $_SERVER['HTTPS'] ) || $_SERVER['HTTPS']!=='on' ){
if( !headers_sent() ){
header( "Status: 301 Moved Permanently" );
header( "Location: $httpsURL" );
exit();
}else{
die( '<script type="javascript">document.location.href="'.$httpsURL.'";</script>' );
}
}
}
Then, as close to the top of these pages which you want to force to connect via PHP, you can require()
a centralised file containing this (and any other) custom functions, and then simply run the forceHTTPS()
function.
I have not implemented this kind of solution personally (I have tended to use the PHP solution, like the one above, for it's simplicity), but the following may be, at least, a good start.
RewriteEngine on
# Check for POST Submission
RewriteCond %{REQUEST_METHOD} !^POST$
# Forcing HTTPS
RewriteCond %{HTTPS} !=on [OR]
RewriteCond %{SERVER_PORT} 80
# Pages to Apply

RewriteRule .* https://%{SERVER_NAME}%{REQUEST_URI} [R=301,L]
# Forcing HTTP
RewriteCond %{HTTPS} =on [OR]

Problem Statement
It's possible to write LINQ to SQL that gets all rows that have either null or an empty string in a given field, but it's not possible to use string.IsNullOrEmpty to do it, even though many other string methods map to LINQ to SQL.
Proposed Solution
Allow string.IsNullOrEmpty in a LINQ to SQL where clause so that these two queries have the same result:
var fieldNullOrEmpty =
from item in db.SomeTable
where item.SomeField == null || item.SomeField.Equals(string.Empty)
select item;
var fieldNullOrEmpty2 =
from item in db.SomeTable
where string.IsNullOrEmpty(item.SomeField)
select item;

I still have a lot to learn about T-SQL, but in working up some code for a transaction (and basing code on examples from stackoverflow and other sites) I found a case where it seems a semicolon is required and if it is missing, the statement does not seem to execute at all and no error is raised. This doesn't seem to be covered in any of the above answers. (This was using MS SQL Server 2012.)
Once I had the transaction working the way I wanted, I decided to put a try-catch around it so if there are any errors it gets rolled back. Only after doing this, the transaction was not committed (SSMS confirms this when trying to close the window with a nice message alerting you to the fact that there is an uncommitted transaction.
So this
COMMIT TRANSACTION
outside a BEGIN TRY/END TRY block worked fine to commit the transaction, but inside the block it had to be
COMMIT TRANSACTION;
Note there is no error or warning provided and no indication that the transaction is still uncommitted until attempting to close the query tab.
Fortunately this causes such a huge problem that it is immediately obvious that there is a problem. Unfortunately since no error (syntax or otherwise) is reported it was not immediately obvious what the problem was.
Contrary-wise, ROLLBACK TRANSACTION seems to work equally well in the BEGIN CATCH block with or without a semicolon.
There may be some logic to this but it feels arbitrary and Alice-in-Wonderland-ish.

The Android Holo Colors Generator allows you to easily create Android components such as EditText
or spinner with your own colours for your Android application. It will generate all necessary nine patch assets plus associated XML drawable and styles which you can copy straight into your project.
http://android-holo-colors.com/
UPDATE 1
This domain seems expired but the project is an open source you can find here
https://github.com/jeromevdl/android-holo-colors
try it
this image put in the background of EditText
android:background="@drawable/textfield_activated"
UPDATE 2
For API 21 or higher, you can use android:backgroundTint
<EditText
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="Underline color change"
android:backgroundTint="@android:color/holo_red_light" />
Update 3
Now We have with back support AppCompatEditText
Note: We need to use app:backgroundTint instead of android:backgroundTint
<android.support.v7.widget.AppCompatEditText
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="Underline color change"
app:backgroundTint="@color/blue_gray_light" />
Update 4 AndroidX version
<androidx.appcompat.widget.AppCompatEditText
app:backgroundTint="@color/blue_gray_light" />
User johannes told you how to do add existing files to a Git repository in a general situation. Because you talk about Bitbucket, I suggest you do the following:
Create a new repository on Bitbucket (you can see a Create button on the top of your profile page) and you will go to this page:
Fill in the form, click next and then you automatically go to this page:
Choose to add existing files and you go to this page:
You use those commands and you upload the existing files to Bitbucket. After that, the files are online.
Web API works very nicely if you accept the fact that you are using HTTP. It's when you start trying to pretend that you are sending objects over the wire that it starts to get messy.
public class TextController : ApiController
{
public HttpResponseMessage Post(HttpRequestMessage request) {
var someText = request.Content.ReadAsStringAsync().Result;
return new HttpResponseMessage() {Content = new StringContent(someText)};
}
}
This controller will handle a HTTP request, read a string out of the payload and return that string back.
You can use HttpClient to call it by passing an instance of StringContent. StringContent will be default use text/plain as the media type. Which is exactly what you are trying to pass.
[Fact]
public void PostAString()
{
var client = new HttpClient();
var content = new StringContent("Some text");
var response = client.PostAsync("http://oak:9999/api/text", content).Result;
Assert.Equal("Some text",response.Content.ReadAsStringAsync().Result);
}

Here is the difference:
This sets the image to half of its original size.
<img src="#" width="173" height="206.5">
This sets the image to half of its available presentation area.
<img src="#" width="50%" height="50%">
For example, if you put this as the only element on the page, it would attempt to take up 50% of the width of the page, thus making it potentially larger than its original size - not half of its original size as you are expecting.
If it is being presented at larger than original size, the image will appear greatly pixelated.
Instead of adding "ws." before every Range, as suggested above, you can add "ws.activate" before Call instead.

As (many) others have pointed out, you can easily hide all UITableViewCell separators by simply turning them off for the entire UITableView itself; eg in your UITableViewController
- (void)viewDidLoad {
...
self.tableView.separatorStyle = UITableViewCellSeparatorStyleNone;
...
}
Unfortunately, its a real PITA to do on a per-cell basis, which is what you are really asking.
Personally, I've tried numerous permutations of changing the cell.separatorInset.left
, again, as (many) others have suggested, but the problem is, to quote Apple (emphasis added):
"...You can use this property to add space between the current cell’s contents and the left and right edges of the table. Positive inset values move the cell content and cell separator inward and away from the table edges..."
So if you try to 'hide' the separator by shoving it offscreen to the right, you can end up also indenting your cell's contentView too. As suggested by crifan, you can then try to compensate for this nasty side-effect by setting cell.indentationWidth
and cell.indentationLevel
appropriately to move everything back, but I've found this to also be unreliable (content still getting indented...).
The most reliable way I've found is to over-ride layoutSubviews
in a simple UITableViewCell subclass and set the right inset so that it hits the left inset, making the separator have 0 width and so invisible [this needs to be done in layoutSubviews to automatically handle rotations]. I also add a convenience method to my subclass to turn this on.
@interface MyTableViewCellSubclass()
@property BOOL separatorIsHidden;
@end
@implementation MyTableViewCellSubclass
- (void)hideSeparator
{
_separatorIsHidden = YES;
}
- (void)layoutSubviews
{
[super layoutSubviews];
if (_separatorIsHidden) {
UIEdgeInsets inset = self.separatorInset;
inset.right = self.bounds.size.width - inset.left;
self.separatorInset = inset;
}
}
@end
Caveat: there isn't a reliable way to restore the original right inset, so you cant 'un-hide' the separator, hence why I'm using an irreversible hideSeparator
method (vs exposing separatorIsHidden). Please note the separatorInset persists across reused cells so, because you can't 'un-hide', you need to keep these hidden-separator cells isolated in their own reuseIdentifier.

Standard C++ won't do much for you in this regard, since path names are platform-specific. You can manually parse the string (as in glowcoder's answer), use operating system facilities (e.g. http://msdn.microsoft.com/en-us/library/aa364232(v=VS.85).aspx ), or probably the best approach, you can use a third-party filesystem library like boost::filesystem.
The easiest way to create the .gitignore file in Windows Explorer is to create a new file named .gitignore.
.
This will skip the validation of having a file extension, since is actually has an empty file extension.
I show you here the easiest way using Vs2017 and Vs2019 Open your xsd with Visual Studio and generate a sample xml file as in the url suggested.
2. Within “XML Schema Explorer” scroll all the way down to find the root/data node. Right click on root/data node and it will show “Generate Sample XML”. If it does not show, it means you are not on the data element node but you are on any of the data definition node.
I had the same issue, tried all changing SSL settings that are provided here. If you are in the corporate network and ssh keys used in such tools like Gerrit. 1. Get your ssh key, 2. Visit Bitbucket and navigate to Profile >> Settings >> SSH Keys >> Add Key.

Some time has passed since most of these answers have been posted and some use now deprecated methods and constants.
I've updated Jarek's code to not use these methods and constants anymore:
protected int getScreenOrientation()
{
Display getOrient = getWindowManager().getDefaultDisplay();
Point size = new Point();
getOrient.getSize(size);
int orientation;
if (size.x < size.y)
{
orientation = Configuration.ORIENTATION_PORTRAIT;
}
else
{
orientation = Configuration.ORIENTATION_LANDSCAPE;
}
return orientation;
}
Note that the mode Configuration.ORIENTATION_SQUARE
isn't supported anymore.
I found this to be reliable on all devices I've tested it on in contrast to the method suggesting the usage of getResources().getConfiguration().orientation
I faced the same problem. Updating bash_profile with the following lines, solved the problem for me:

I was getting this error with Laravel Sanctum. I fixed it by adding \Illuminate\Session\Middleware\StartSession::class,
to the api
middleware group in Kernel.php, but I later figured out this "worked" because my authentication routes were added in api.php
instead of web.php
, so Laravel was using the wrong auth guard.
I moved these routes here into web.php
and then they started working properly with the AuthenticatesUsers.php
trait:
Route::group(['middleware' => ['guest', 'throttle:10,5']], function () {
Route::post('register', 'Auth\RegisterController@register')->name('register');
Route::post('login', 'Auth\LoginController@login')->name('login');
Route::post('password/email', 'Auth\ForgotPasswordController@sendResetLinkEmail');
Route::post('password/reset', 'Auth\ResetPasswordController@reset');
Route::post('email/verify/{user}', 'Auth\VerificationController@verify')->name('verification.verify');
Route::post('email/resend', 'Auth\VerificationController@resend');
Route::post('oauth/{driver}', 'Auth\OAuthController@redirectToProvider')->name('oauth.redirect');
Route::get('oauth/{driver}/callback', 'Auth\OAuthController@handleProviderCallback')->name('oauth.callback');
});
Route::post('logout', 'Auth\LoginController@logout')->name('logout');
I figured out the problem after I got another weird error about RequestGuard::logout()
does not exist.
It made me realize that my custom auth routes are calling methods from the AuthenticatesUsers trait, but I wasn't using Auth::routes()
to accomplish it. Then I realized Laravel uses the web guard by default and that means routes should be in routes/web.php
.
This is what my settings look like now with Sanctum and a decoupled Vue SPA app:
Kernel.php
protected $middlewareGroups = [
'web' => [
\App\Http\Middleware\EncryptCookies::class,
\Illuminate\Cookie\Middleware\AddQueuedCookiesToResponse::class,
\Illuminate\Session\Middleware\StartSession::class,
// \Illuminate\Session\Middleware\AuthenticateSession::class,
\Illuminate\View\Middleware\ShareErrorsFromSession::class,
\App\Http\Middleware\VerifyCsrfToken::class,
\Illuminate\Routing\Middleware\SubstituteBindings::class,
],
'api' => [
EnsureFrontendRequestsAreStateful::class,
\Illuminate\Routing\Middleware\SubstituteBindings::class,
'throttle:60,1',
],
];
Note: With Laravel Sanctum and same-domain Vue SPA, you use httpOnly cookies for session cookie, and remember me cookie, and unsecure cookie for CSRF, so you use the
web
guard for auth, and every other protected, JSON-returning route should useauth:sanctum
middleware.
config/auth.php
'defaults' => [
'guard' => 'web',
'passwords' => 'users',
],
...
'guards' => [
'web' => [
'driver' => 'session',
'provider' => 'users',
],
'api' => [
'driver' => 'token',
'provider' => 'users',
'hash' => false,
],
],
Then you can have unit tests such as this, where critically, Auth::check()
, Auth::user()
, and Auth::logout()
work as expected with minimal config and maximal usage of AuthenticatesUsers
and RegistersUsers
traits.
Here are a couple of my login unit tests:
TestCase.php
/**
* Creates and/or returns the designated regular user for unit testing
*
* @return \App\User
*/
public function user() : User
{
$user = User::query()->firstWhere('email', '[email protected]');
if ($user) {
return $user;
}
// User::generate() is just a wrapper around User::create()
$user = User::generate('Test User', '[email protected]', self::AUTH_PASSWORD);
return $user;
}
/**
* Resets AuthManager state by logging out the user from all auth guards.
* This is used between unit tests to wipe cached auth state.
*
* @param array $guards
* @return void
*/
protected function resetAuth(array $guards = null) : void
{
$guards = $guards ?: array_keys(config('auth.guards'));
foreach ($guards as $guard) {
$guard = $this->app['auth']->guard($guard);
if ($guard instanceof SessionGuard) {
$guard->logout();
}
}
$protectedProperty = new \ReflectionProperty($this->app['auth'], 'guards');
$protectedProperty->setAccessible(true);
$protectedProperty->setValue($this->app['auth'], []);
}
LoginTest.php
protected $auth_guard = 'web';
/** @test */
public function it_can_login()
{
$user = $this->user();
$this->postJson(route('login'), ['email' => $user->email, 'password' => TestCase::AUTH_PASSWORD])
->assertStatus(200)
->assertJsonStructure([
'user' => [
...expectedUserFields,
],
]);
$this->assertEquals(Auth::check(), true);
$this->assertEquals(Auth::user()->email, $user->email);
$this->assertAuthenticated($this->auth_guard);
$this->assertAuthenticatedAs($user, $this->auth_guard);
$this->resetAuth();
}
/** @test */
public function it_can_logout()
{
$this->actingAs($this->user())
->postJson(route('logout'))
->assertStatus(204);
$this->assertGuest($this->auth_guard);
$this->resetAuth();
}
I overrided the registered
and authenticated
methods in the Laravel auth traits so that they return the user object instead of just the 204 OPTIONS:
public function authenticated(Request $request, User $user)
{
return response()->json([
'user' => $user,
]);
}
protected function registered(Request $request, User $user)
{
return response()->json([
'user' => $user,
]);
}
Look at the vendor code for the auth traits. You can use them untouched, plus those two above methods.
Here is my Vue SPA's Vuex actions for login:
async login({ commit }, credentials) {
try {
const { data } = await axios.post(route('login'), {
...credentials,
remember: credentials.remember || undefined,
});
commit(FETCH_USER_SUCCESS, { user: data.user });
commit(LOGIN);
return commit(CLEAR_INTENDED_URL);
} catch (err) {
commit(LOGOUT);
throw new Error(`auth/login# Problem logging user in: ${err}.`);
}
},
async logout({ commit }) {
try {
await axios.post(route('logout'));
return commit(LOGOUT);
} catch (err) {
commit(LOGOUT);
throw new Error(`auth/logout# Problem logging user out: ${err}.`);
}
},
It took me over a week to get Laravel Sanctum + same-domain Vue SPA + auth unit tests all working up to my standard, so hopefully my answer here can help save others time in the future.
even shorter:
Array.apply(null, Array(8)).map(function() {
var c = 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789';
return c.charAt(Math.random() * c.length);
}).join('');
or as function:
function generatePassword(length, charSet) {
charSet = charSet ? charSet : 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789^°!"§$%&/()=?`*+~\'#,;.:-_';
return Array.apply(null, Array(length || 10)).map(function() {
return charSet.charAt(Math.random() * charSet.length);
}).join('');
}
Surprisingly, square brackets in DocumentRoot (and related, like <Directory>) paths can also cause error 403:
DocumentRoot "P:/TRY/web/fatfree/from_github/fatfree-master[bang]"
failed with 403, whileDocumentRoot "P:/TRY/web/fatfree/from_github/fatfree-master"
worked fine.(I didn't bother figuring out the Apache path escaping, if any, just renamed the path instead. If anyone knows, comments are welcome.)
I have provided two approaches to solve the same issue,
Solution 1: This approach includes 2 steps, first create a temporary table with specified data type, next insert the value from the existing data table.
CREATE TABLE #TempStudent(tempID int, tempName varchar(MAX) )
INSERT INTO #TempStudent(tempID, tempName) SELECT id, studName FROM students where id =1
SELECT * FROM #TempStudent
Solution 2: This approach is simple, where you can directly insert the values to temporary table, where automatically the system take care of creating the temp table with the same data type of original table.
SELECT id, studName INTO #TempStudent FROM students where id =1
SELECT * FROM #TempStudent
Another feature:
instead of of server.xml, you can add "Resource" tag in
your_application/META-INF/Context.xml
(according to tomcat docs)
like this:
<Context>
<Resource name="jdbc/DatabaseName" auth="Container" type="javax.sql.DataSource"
username="dbUsername" password="dbPasswd"
url="jdbc:postgresql://localhost/dbname"
driverClassName="org.postgresql.Driver"
initialSize="5" maxWait="5000"
maxActive="120" maxIdle="5"
validationQuery="select 1"
poolPreparedStatements="true"/>
</Context>
Disclaimer: While the top answer is probably a better solution, as a beginner it's a lot to take in when all you want is something very simple. This is intended as a more direct answer to your original question "How can I select certain elements in React"
I think the confusion in your question is because you have React components which you are being passed the id "Progress1", "Progress2" etc. I believe this is not setting the html attribute 'id', but the React component property. e.g.
class ProgressBar extends React.Component {
constructor(props) {
super(props)
this.state = {
id: this.props.id <--- ID set from <ProgressBar id="Progress1"/>
}
}
}
As mentioned in some of the answers above you absolutely can use document.querySelector
inside of your React app, but you have to be clear that it is selecting the html output of your components' render methods. So assuming your render output looks like this:
render () {
const id = this.state.id
return (<div id={"progress-bar-" + id}></div>)
}
Then you can elsewhere do a normal javascript querySelector call like this:
let element = document.querySelector('#progress-bar-Progress1')
We have been using jqGrid on a project and have had some good luck with it. Lots of options for inline editing, etc. If that stuff isn't necessary, then we've just used a plain foreach loop like @Hrvoje.
You can use a forward to have clean code, based on two things:
Type of arguments (when calling the function)
function myFunc(){
return window['myFunc_'+arguments.length+Array.from(arguments).map((arg)=>typeof arg).join('_')](...arguments);
}
/** one argument & this argument is string */
function myFunc_1_string(){

Here is improved @lucasjones answer. I included improvements mentioned in comment section after his answer. I hope someone will find this useful.
public static string[] GetTypePropertyNames(object classObject, BindingFlags bindingFlags)
{
if (classObject == null)
{
throw new ArgumentNullException(nameof(classObject));
}
var type = classObject.GetType();
var propertyInfos = type.GetProperties(bindingFlags);
return propertyInfos.Select(propertyInfo => propertyInfo.Name).ToArray();
}
Any time you do a remove() or a removeAll(), you should call
validate();
repaint();
after you have completed add()'ing the new components.
Calling validate() or revalidate() is mandatory when you do a remove() - see the relevant javadocs.
My own testing indicates that repaint() is also necessary. I'm not sure exactly why.
I have experience this issue in past. Based on that I can say that generally we get this issue if your dataset has multiple fieldnames that points to same field source. Take a look into following posts for detail error description
http://www.bi-rootdata.com/2012/09/an-error-occurred-during-report.html
http://www.bi-rootdata.com/2012/09/an-item-with-same-key-has-already-been.html
In your case, you should check your all field names returned by Sp prc_RPT_Select_BI_Completes_Data_View and make sure that all fields has unique name.
You can also use the jsPDF-AutoTable plugin. You can check out a demo here that uses the following code.
var doc = new jsPDF('p', 'pt');
var elem = document.getElementById("basic-table");
var res = doc.autoTableHtmlToJson(elem);
doc.autoTable(res.columns, res.data);
doc.save("table.pdf");
Check your Keychain - look in Login and System keychains for expired certificates or error messages.
I found certs with "this certificate has an invalid user" error messages, and an expired Apple Worldwide Developer Relations Certificate.
Delete them and install the new AWDRC certificate from https://developer.apple.com/certificationauthority/AppleWWDRCA.cer
Then follow the accepted answer to get Xcode to use the new certificates.
I solved the problem in june of 2017 changing the play-services versions for the latest firebase versions (9.6.1). When I used the latest play-services version (10.2.4) I got that error. The code in the gradle looks like this:
Before
compile 'com.google.android.gms:play-services-maps:10.2.4'
compile 'com.google.android.gms:play-services-places:10.2.4'
compile 'com.google.firebase:firebase-core:9.6.1'
compile 'com.google.firebase:firebase-auth:9.6.1'
After
compile 'com.google.android.gms:play-services-maps:9.6.1'
compile 'com.google.android.gms:play-services-places:9.6.1'
compile 'com.google.firebase:firebase-core:9.6.1'
compile 'com.google.firebase:firebase-auth:9.6.1'
XDocument xdoc = XDocument.Load("data.xml");
var lv1s = xdoc.Root.Descendants("level1");
var lvs = lv1s.SelectMany(l=>
new string[]{ l.Attribute("name").Value }
.Union(
l.Descendants("level2")
.Select(l2=>" " + l2.Attribute("name").Value)
)
);
foreach (var lv in lvs)
{
result.AppendLine(lv);
}
Ps. You have to use .Root on any of these versions.
You can get the HTML of the website with driver.getPageSource(). If the html does not change in a given interval of time this means that the page is done loading. One or two seconds should be enough. If you want to speed things up you can just compare the lenght of the two htmls. If their lenght is equal the htmls should be equal and that means the page is fully loaded. The JavaScript solution did not work for me.
I've faced the same problem, followed these instructions and it worked for me:
python -m pip install --upgrade pip
(to upgrade pip)pip3 install djangorestframework
Added rest_framework
as first app:
INSTALLED_APPS = [
'rest_framework',
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
#apps
'apps.endpoints',

I made this generic state machine out of Juliet's code. It's working awesome for me.
These are the benefits:
TState
and TCommand
, TransitionResult<TState>
to have more control over the output results of [Try]GetNext()
methodsStateTransition
only through AddTransition(TState, TCommand, TState)
making it easier to work with itCode:
public class StateMachine<TState, TCommand>
where TState : struct, IConvertible, IComparable
where TCommand : struct, IConvertible, IComparable
{
protected class StateTransition<TS, TC>
where TS : struct, IConvertible, IComparable
where TC : struct, IConvertible, IComparable
{
readonly TS CurrentState;
readonly TC Command;
public StateTransition(TS currentState, TC command)
{
if (!typeof(TS).IsEnum || !typeof(TC).IsEnum)
{
throw new ArgumentException("TS,TC must be an enumerated type");
}
CurrentState = currentState;
Command = command;
}
public override int GetHashCode()
{
return 17 + 31 * CurrentState.GetHashCode() + 31 * Command.GetHashCode();
}
public override bool Equals(object obj)
{
StateTransition<TS, TC> other = obj as StateTransition<TS, TC>;
return other != null
&& this.CurrentState.CompareTo(other.CurrentState) == 0
&& this.Command.CompareTo(other.Command) == 0;
}
}
private Dictionary<StateTransition<TState, TCommand>, TState> transitions;
public TState CurrentState { get; private set; }
protected StateMachine(TState initialState)
{
if (!typeof(TState).IsEnum || !typeof(TCommand).IsEnum)
{
throw new ArgumentException("TState,TCommand must be an enumerated type");
}
CurrentState = initialState;
transitions = new Dictionary<StateTransition<TState, TCommand>, TState>();
}
/// <summary>
/// Defines a new transition inside this state machine
/// </summary>
/// <param name="start">source state</param>
/// <param name="command">transition condition</param>
/// <param name="end">destination state</param>
protected void AddTransition(TState start, TCommand command, TState end)
{
transitions.Add(new StateTransition<TState, TCommand>(start, command), end);
}
public TransitionResult<TState> TryGetNext(TCommand command)
{
StateTransition<TState, TCommand> transition = new StateTransition<TState, TCommand>(CurrentState, command);
TState nextState;
if (transitions.TryGetValue(transition, out nextState))
return new TransitionResult<TState>(nextState, true);
else
return new TransitionResult<TState>(CurrentState, false);
}
public TransitionResult<TState> MoveNext(TCommand command)
{
var result = TryGetNext(command);
if(result.IsValid)
{
//changes state
CurrentState = result.NewState;
}
return result;
}
}
This is the return type of TryGetNext method:
public struct TransitionResult<TState>
{
public TransitionResult(TState newState, bool isValid)
{
NewState = newState;
IsValid = isValid;
}
public TState NewState;
public bool IsValid;
}
This is how you can create a OnlineDiscountStateMachine
from the generic class:
Define an enum OnlineDiscountState
for its states and an enum OnlineDiscountCommand
for its commands.
Define a class OnlineDiscountStateMachine
derived from the generic class using those two enums
Derive the constructor from base(OnlineDiscountState.InitialState)
so that the initial state is set to OnlineDiscountState.InitialState
Use AddTransition
as many times as needed
public class OnlineDiscountStateMachine : StateMachine<OnlineDiscountState, OnlineDiscountCommand>
{
public OnlineDiscountStateMachine() : base(OnlineDiscountState.Disconnected)
{
AddTransition(OnlineDiscountState.Disconnected, OnlineDiscountCommand.Connect, OnlineDiscountState.Connected);
AddTransition(OnlineDiscountState.Disconnected, OnlineDiscountCommand.Connect, OnlineDiscountState.Error_AuthenticationError);
AddTransition(OnlineDiscountState.Connected, OnlineDiscountCommand.Submit, OnlineDiscountState.WaitingForResponse);
AddTransition(OnlineDiscountState.WaitingForResponse, OnlineDiscountCommand.DataReceived, OnlineDiscountState.Disconnected);
}
}
use the derived state machine
odsm = new OnlineDiscountStateMachine();
public void Connect()
{
var result = odsm.TryGetNext(OnlineDiscountCommand.Connect);
//is result valid?
if (!result.IsValid)
//if this happens you need to add transitions to the state machine
//in this case result.NewState is the same as before
Console.WriteLine("cannot navigate from this state using OnlineDiscountCommand.Connect");
//the transition was successfull
//show messages for new states
else if(result.NewState == OnlineDiscountState.Error_AuthenticationError)
Console.WriteLine("invalid user/pass");
else if(result.NewState == OnlineDiscountState.Connected)
Console.WriteLine("Connected");
else
Console.WriteLine("not implemented transition result for " + result.NewState);
}
My windows firewall was blocking port 8080 so i changed it to 5000 and it worked!
I also had the same problem, I had assumed that Laravel is installed "out of the box" but it seems it isn't. I SSH'ed to the machine and ran these commands:
cd Code
sudo composer self-update #not necessary, but I did it anyways
composer create-project laravel/laravel Laravel --prefer-dist
And everything was running as usual.
Currently, i prefer using this methods:
String data = "Date from Register: ";
if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.O) {
// Verify that OS.Version is > API 26 (OREO)
DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyyMMdd");
// Origin format
LocalDate localDate = LocalDate.parse(capitalModels.get(position).getDataServer(), formatter); // Parse String (from server) to LocalDate
DateTimeFormatter formatter1 = DateTimeFormatter.ofPattern("dd/MM/yyyy");
//Output format
data = "Data de Registro: "+formatter1.format(localDate); // Output
Toast.makeText(holder.itemView.getContext(), data, Toast.LENGTH_LONG).show();
}else{
//Same resolutions, just use legacy methods to oldest android OS versions.
SimpleDateFormat format = new SimpleDateFormat("yyyyMMdd",Locale.getDefault());
try {
Date date = format.parse(capitalModels.get(position).getDataServer());
SimpleDateFormat formatter = new SimpleDateFormat("dd/MM/yyyy", Locale.getDefault());
data = "Date from Register: "+formatter.format(date);
} catch (ParseException e) {
e.printStackTrace();
}
}
If you use a TextField with rounded corners use this code:
self.TextField.layer.cornerRadius=8.0f;
self.TextField.layer.masksToBounds=YES;
self.TextField.layer.borderColor=[[UIColor redColor]CGColor];
self.TextField.layer.borderWidth= 1.0f;
To remove the border:
self.TextField.layer.masksToBounds=NO;
self.TextField.layer.borderColor=[[UIColor clearColor]CGColor];
Considering that your package scanning is correctly set either through XML configuration or annotation based configuration.
You will need a @Repository
on your ClientRepository
implementation as well to allow Spring to use it in an @Autowired
. Since it's not here we can only suppose that's what's missing.
As a side note, it would be cleaner to put your @Autowired
/@Qualifier
directly on your member if the setter method is only used for the @Autowired
.
@Autowired
@Qualifier("clientRepository")
private ClientRepository clientRepository;
Lastly, you don't need the @Qualifier
is there is only one class implementing the bean definition so unless you have several implementation of ClientService
and ClientRepository
you can remove the @Qualifier
node --max_old_space_size=4096 ./node_modules/@angular/cli/bin/ng build --prod --build-optimizer
adding parameter --build-optimizer
resolved the issue in my case.
Update:
I am not sure why adding only --build-optimizer solves the issue but as per angular docs it should be used with aot enabled, so updated command should be like below
--build-optimizer=true --aot=true
(Since everyone is taking a shot at this). Here's my version (with null checks, and correct input and replacement escaping) ** Inspired from around the internet and other versions:
using System;
using System.Text.RegularExpressions;
public static class MyExtensions {
public static string ReplaceIgnoreCase(this string search, string find, string replace) {
return Regex.Replace(search ?? "", Regex.Escape(find ?? ""), (replace ?? "").Replace("$", "$$"), RegexOptions.IgnoreCase);
}
}
Usage:
var result = "This is a test".ReplaceIgnoreCase("IS", "was");
If you want to change buttons text color (positive, negative, neutral) just add to your custom dialog style:
<item name="colorAccent">@color/accent_color</item>
So, your dialog style must looks like this:
<style name="AlertDialog" parent="Theme.AppCompat.Light.Dialog.Alert">
<item name="android:textColor">@android:color/black</item>
<item name="colorAccent">@color/topeka_accent</item>
</style>
If you have the option pre-existing in a fixed-with <select>
, and you don't want to change the width programmatically, you could be out of luck unless you get a little creative.
title
attribute to each option. This is non-standard HTML (if you care for this minor infraction here), but IE (and Firefox as well) will display the entire text in a mouse popup on mouse hover.If you are adding a long option later through JavaScript, look here: How to update HTML “select” box dynamically in IE
I needed to solve this problem too when Django was displaying Decimal type values in a text field. E.g. when '1' was the value. It would show '1.00000000'. If '1.23' was the value, it would show '1.23000000' (In the case of a 'decimal_places' setting of 8)
Using parseFloat was not an option for me since it is possible it does not return the exact same value. toFixed was not an option since I did not want to round anything, so I created a function:
function removeTrailingZeros(value) {
value = value.toString();
# if not containing a dot, we do not need to do anything
if (value.indexOf('.') === -1) {
return value;
}
# as long as the last character is a 0 or a dot, remove it
while((value.slice(-1) === '0' || value.slice(-1) === '.') && value.indexOf('.') !== -1) {
value = value.substr(0, value.length - 1);
}
return value;
}
Copying files byte-by-byte does work, but is slow and wasteful on modern UNIXes. Modern UNIXes have “copy-on-write” support built-in to the filesystem: a system call makes a new directory entry pointing at the existing bytes on disk, and no file content bytes on disk are touched until one of the copies is modified, at which point only the changed blocks are written to disk. This allows near-instant file copies that use no additional file blocks, regardless of file size. For example, here are some details about how this works in xfs.
On linux, use the FICLONE
ioctl
as coreutils cp now does by default.
#ifdef FICLONE
return ioctl (dest_fd, FICLONE, src_fd);
#else
errno = ENOTSUP;
return -1;
#endif
On macOS, use clonefile(2) for instant copies on APFS volumes. This is what Apple’s cp -c
uses. The docs are not completely clear but it is likely that copyfile(3) with COPYFILE_CLONE
also uses this. Leave a comment if you’d like me to test that.
In case these copy-on-write operations are not supported—whether the OS is too old, the underlying file system does not support it, or because you are copying files between different filesystems—you do need to fall back to trying sendfile, or as a last resort, copying byte-by-byte. But to save everyone a lot of time and disk space, please give FICLONE
and clonefile(2)
a try first.
Try this..
Dim S As String
S = "RAJAN"
Dim answer As Char
answer = S.Substring(0, 1)
In one of my machine, delimiting the word with "\b
" (without the quotes) did not work. The solution was to use "\<
" for starting delimiter and "\>
" for ending delimiter.
To explain with Joakim Lundberg's example:
$ echo "bar embarassment" | sed "s/\<bar\>/no bar/g"
no bar embarassment
Just browse up to your installation's directory and execute this file "pg_env.bat", so after go at bin folder and execute pgAdmin.exe. This must work no doubt!
if you want to check if your passed string is in string then there is a simple method for that.
string yourStringForCheck= "abc";
string stringInWhichWeCheck= "Test abc abc";
bool isContained = stringInWhichWeCheck.ToLower().IndexOf(yourStringForCheck.ToLower()) > -1;
This boolean value will return if the string is contained or not
I came with a pretty simple solution. I'm not sure whether it is the correct way to do it but it works in a practical sense. Let's directly watch what we want to be rendered. For example in a directive that includes some ng-repeat
s, I would watch out for the length of text (you may have other things!) of paragraphs or the whole html. The directive will be like this:
.directive('myDirective', [function () {
'use strict';
return {
link: function (scope, element, attrs) {
scope.$watch(function(){
var whole_p_length = 0;
var ps = element.find('p');
for (var i=0;i<ps.length;i++){
if (ps[i].innerHTML == undefined){
continue
}
whole_p_length+= ps[i].innerHTML.length;
}
//it could be this too: whole_p_length = element[0].innerHTML.length; but my test showed that the above method is a bit faster
console.log(whole_p_length);
return whole_p_length;
}, function (value) {
//Code you want to be run after rendering changes
});
}
}]);
NOTE that the code actually runs after rendering changes rather complete rendering. But I guess in most cases you can handle the situations whenever rendering changes happen. Also you could think of comparing this p
s length (or any other measure) with your model if you want to run your code only once after rendering completed. I appreciate any thoughts/comments on this.
Try this;
public String toDate() {
DateFormat dateFormat = new SimpleDateFormat("yyyy/MM/dd HH:mm:ss");
Calendar cal = Calendar.getInstance();
cal.add(Calendar.DATE, -1);
return dateFormat.format(cal.getTime());
}
HttpClient was deprecated in API Level 22 and removed in API Level 23.
You have to use URLConnection
.
In SQL Server, you would say:
Select name from users
UNION [ALL]
SELECT 'JASON'
In Oracle, you would say
Select name from user
UNION [ALL]
Select 'JASON' from DUAL
The question is answered already, but I want add more information about the causes.

findViewById()
of non existing viewLike when you use findViewById(R.id.button)
when button id does not exist in layout XML.
If you wrong cast some class, then you get this error. Like you cast RelativeLayout
to LinearLayout
or EditText
to TextView
.
manifest.xml
If you did not register Activity in manifest.xml
then this error comes.
findViewById()
with declaration at top levelBelow code is incorrect. This will create error. Because you should do findViewById()
after calling setContentView()
. Because an View can be there after it is created.
public class MainActivity extends Activity {
ImageView mainImage = (ImageView) findViewById(R.id.imageViewMain); //incorrect way
@Override
protected void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mainImage = (ImageView) findViewById(R.id.imageViewMain); //correct way
//...
}
}
abstract
Activity class.When you try to start an Activity which is abstract, you will will get this error. So just remove abstract
keyword before activity class name.
If your activity is written in Kotlin and you have not setup kotlin in your app. then you will get error. You can follow simple steps as written in Android Link or Kotlin Link. You can check this answer too.
Read about Downcast and Upcast
You don't want to delete if you're wanting to leave the row itself intact. You want to update the row, and change the column value.
The general form for this would be an UPDATE
statement:
UPDATE <table name>
SET
ColumnA = <NULL, or '', or whatever else is suitable for the new value for the column>
WHERE
ColumnA = <bad value> /* or any other search conditions */
Float them both the same way and add the margin of 40px. If you have 2 elements floating opposite ways you will have much less control and the containing element will determine how far apart they are.
#left{
float: left;
margin-right: 40px;
}
#right{
float: left;
}
If You need the text to be centered, and the image to be besides it, like this:
Then You can achieve it with this widget tree:
RaisedButton(
onPressed: () {},
child: Row(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
children: <Widget>[
Expanded(child: Text(
'Push it! '*10,
textAlign: TextAlign.center,
),),
Image.network(
'https://picsum.photos/250?image=9',
),
],
),
),
You basically have 3 options to prevent the PowerShell Console window from closing, that I describe in more detail on my blog post.
PowerShell -NoExit "C:\SomeFolder\SomeScript.ps1"
Read-Host -Prompt "Press Enter to exit"
Global Fix: Change your registry key to always leave the PowerShell Console window open after the script finishes running. Here's the 2 registry keys that would need to be changed:
? Open With ? Windows PowerShell
When you right-click a .ps1 file and choose Open With
Registry Key: HKEY_CLASSES_ROOT\Applications\powershell.exe\shell\open\command
Default Value:
"C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe" "%1"
Desired Value:
"C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe" "& \"%1\""
? Run with PowerShell
When you right-click a .ps1 file and choose Run with PowerShell (shows up depending on which Windows OS and Updates you have installed).
Registry Key: HKEY_CLASSES_ROOT\Microsoft.PowerShellScript.1\Shell\0\Command
Default Value:
"C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe" "-Command" "if((Get-ExecutionPolicy ) -ne 'AllSigned') { Set-ExecutionPolicy -Scope Process Bypass }; & '%1'"
Desired Value:
"C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe" -NoExit "-Command" "if((Get-ExecutionPolicy ) -ne 'AllSigned') { Set-ExecutionPolicy -Scope Process Bypass }; & \"%1\""
You can download a .reg file from my blog to modify the registry keys for you if you don't want to do it manually.
It sounds like you likely want to use option #2. You could even wrap your whole script in a try block, and only prompt for input if an error occurred, like so:
try
{
# Do your script's stuff
}
catch
{
Write-Error $_.Exception.ToString()
Read-Host -Prompt "The above error occurred. Press Enter to exit."
}

You can use a HashingStrategy based Map
from Eclipse Collections
HashingStrategy<String> hashingStrategy =
HashingStrategies.fromFunction(String::toUpperCase);
MutableMap<String, String> node = HashingStrategyMaps.mutable.of(hashingStrategy);
Note: I am a contributor to Eclipse Collections.
If you want to use the GUI... click/double-click the table and select the Data
tab. Click in the column value you want to set to (null)
. Select the value and delete it. Hit the commit button (green check-mark button). It should now be null.

You'll have to create a custom object for that. Your custom object will contain two values:
Not sure if there already is a CLR-provided data type that has that, but at least the TimeZone component is already available.
All of the answers above break expected browser behavior. What most people want is something that will scroll to the top if it's a "new" page, but return to the previous position if you're getting there through the Back (or Forward) button.
If you assume HTML5 mode, this turns out to be easy (although I'm sure some bright folks out there can figure out how to make this more elegant!):
// Called when browser back/forward used
window.onpopstate = function() {
$timeout.cancel(doc_scrolling);
};
// Called after ui-router changes state (but sadly before onpopstate)
$scope.$on('$stateChangeSuccess', function() {
doc_scrolling = $timeout( scroll_top, 50 );
// Moves entire browser window to top
scroll_top = function() {
document.body.scrollTop = document.documentElement.scrollTop = 0;
}
The way it works is that the router assumes it is going to scroll to the top, but delays a bit to give the browser a chance to finish up. If the browser then notifies us that the change was due to a Back/Forward navigation, it cancels the timeout, and the scroll never occurs.
I used raw document
commands to scroll because I want to move to the entire top of the window. If you just want your ui-view
to scroll, then set autoscroll="my_var"
where you control my_var
using the techniques above. But I think most people will want to scroll the entire page if you are going to the page as "new".
The above uses ui-router, though you could use ng-route instead by swapping $routeChangeSuccess
for$stateChangeSuccess
.
Here is a simple jQuery UI solution based on the example here:
http://jqueryui.com/button/#radio
Modified code:
<!doctype html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>jQuery UI Button - Radios</title>
<link rel="stylesheet" href="//code.jquery.com/ui/1.11.3/themes/smoothness/jquery-ui.css">
<script src="//code.jquery.com/jquery-1.10.2.js"></script>
<script src="//code.jquery.com/ui/1.11.3/jquery-ui.js"></script>
<link rel="stylesheet" href="/resources/demos/style.css">
<script>
$(function() {
$( "#radio" ).buttonset();
});
</script>
</head>
<body>
<form>
<div id="radio">
<input type="radio" id="radio1" name="radio"><label for="radio1"><img src="image1.gif" /></label>
<input type="radio" id="radio2" name="radio" checked="checked"><label for="radio2"><img src="image2.gif" /></label>
<input type="radio" id="radio3" name="radio"><label for="radio3"><img src="image3.gif" /></label>
</div>
</form>
</body>
</html>
jQueryUI takes care of the image background so you know which button is checked.
Beware: If you want to set a button to checked or unchecked via Javascript, you must call the refresh function:
$('#radio3').prop('checked', true).button("refresh");
By far the easiest method is to subtract one date from the other and compare the result.
var oDateOne = new Date();_x000D_
var oDateTwo = new Date();_x000D_
_x000D_
alert(oDateOne - oDateTwo === 0);_x000D_
alert(oDateOne - oDateTwo < 0);_x000D_
alert(oDateOne - oDateTwo > 0);
_x000D_
Java is pass by constant reference where a copy of the reference is passed which means that it is basically a pass by value. You might change the contents of the reference if the class is mutable but you cannot change the reference itself. In other words the address can not be changed since it is passed by value but the content that is pointed by the address can be changed. In case of immutable classes, the content of the reference cannot be changed either.
Use ViewCompat.setBackground(view, background);
try:
select * from table 1 left join table2 as t on 1 = 1;
This will bring all the columns from both the table.
select regexp_replace(field, E'[\\n\\r\\u2028]+', ' ', 'g' )
I had the same problem in my postgres d/b, but the newline in question wasn't the traditional ascii CRLF, it was a unicode line separator, character U2028. The above code snippet will capture that unicode variation as well.
Update... although I've only ever encountered the aforementioned characters "in the wild", to follow lmichelbacher's advice to translate even more unicode newline-like characters, use this:
select regexp_replace(field, E'[\\n\\r\\f\\u000B\\u0085\\u2028\\u2029]+', ' ', 'g' )
There is a mistake in your insert statement chage it to below and try :
String sql = "insert into table_name values ('" + Col1 +"','" + Col2 + "','" + Col3 + "')";
In a Spring project you can use
UriComponentsBuilder.fromHttpRequest(new ServletServerHttpRequest(request)).build().toUriString()
Tweaked version from Techie Delight:
#include <string>
#include <vector>
std::vector<std::string> split(const std::string& str, char delim) {
std::vector<std::string> strings;
size_t start;
size_t end = 0;
while ((start = str.find_first_not_of(delim, end)) != std::string::npos) {
end = str.find(delim, start);
strings.push_back(str.substr(start, end - start));
}
return strings;
}
Ok, here is the JS code:
var data = JSON.parse('{"c":{"a":{"name":"cable - black","value":2}}}')
for (var event in data) {
var dataCopy = data[event];
for (data in dataCopy) {
var mainData = dataCopy[data];
for (key in mainData) {
if (key.match(/name|value/)) {
alert('key : ' + key + ':: value : ' + mainData[key])
}
}
}
}?
It is mainly a performance issue.
Having strings behave LIKE value type helps when writing code, but having it BE a value type would make a huge performance hit.
For an in-depth look, take a peek at a nice article on strings in the .net framework.
Swift 3.0
If you don't want to show user location in map, but just want to store it in firebase or some where else then follow this steps,
import MapKit
import CoreLocation
Now use CLLocationManagerDelegate on your VC and you must override the last three methods shown below. You can see how the requestLocation() method will get you the current user location using these methods.
class MyVc: UIViewController, CLLocationManagerDelegate {
let locationManager = CLLocationManager()
override func viewDidLoad() {
super.viewDidLoad()
isAuthorizedtoGetUserLocation()
if CLLocationManager.locationServicesEnabled() {
locationManager.delegate = self
locationManager.desiredAccuracy = kCLLocationAccuracyNearestTenMeters
}
}
//if we have no permission to access user location, then ask user for permission.
func isAuthorizedtoGetUserLocation() {
if CLLocationManager.authorizationStatus() != .authorizedWhenInUse {
locationManager.requestWhenInUseAuthorization()
}
}
//this method will be called each time when a user change his location access preference.
func locationManager(_ manager: CLLocationManager, didChangeAuthorization status: CLAuthorizationStatus) {
if status == .authorizedWhenInUse {
print("User allowed us to access location")
//do whatever init activities here.
}
}
//this method is called by the framework on locationManager.requestLocation();
func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
print("Did location updates is called")
//store the user location here to firebase or somewhere
}
func locationManager(_ manager: CLLocationManager, didFailWithError error: Error) {
print("Did location updates is called but failed getting location \(error)")
}
}
Now you can code the below call once user sign in to your app. When requestLocation() is invoked it will further invoke didUpdateLocations above and you can store the location to Firebase or anywhere else.
if CLLocationManager.locationServicesEnabled() {
locationManager.requestLocation();
}
if you are using GeoFire then in the didUpdateLocations method above you can store the location as below
geoFire?.setLocation(locations.first, forKey: uid) where uid is the user id who logged in to the app. I think you will know how to get UID based on your app sign in implementation.
Last but not least, go to your Info.plist and enable "Privacy -Location when in Use Usage Description."
When you use simulator to test it always give you one custom location that you configured in Simulator -> Debug -> Location.
The mappedBy
attribute is referencing customer
while the property is mCustomer
, hence the error message. So either change your mapping into:
/** The collection of stores. */
@OneToMany(mappedBy = "mCustomer", cascade = CascadeType.ALL, fetch = FetchType.LAZY)
private Collection<Store> stores;
Or change the entity property into customer
(which is what I would do).
The mappedBy reference indicates "Go look over on the bean property named 'customer' on the thing I have a collection of to find the configuration."
Try Date.now().
The skipping is most likely due to garbage collection. Typically garbage collection can be avoided by reusing variables as much as possible, but I can't say specifically what methods you can use to reduce garbage collection pauses.
this is my take on a random number in a range, as in I wanted to get a random number within a range of base to exponent. e.g. base = 10, exponent = 2, gives a random number from 0 to 100, ideally, and so on.
if it helps use it, here it is:
// get random number within provided base + exponent
// by Goran Biljetina --> 2012
function isEmpty(value){
return (typeof value === "undefined" || value === null);
}
var numSeq = new Array();
function add(num,seq){
var toAdd = new Object();
toAdd.num = num;
toAdd.seq = seq;
numSeq[numSeq.length] = toAdd;
}
function fillNumSeq (num,seq){
var n;
for(i=0;i<=seq;i++){
n = Math.pow(num,i);
add(n,i);
}
}
function getRandNum(base,exp){
if (isEmpty(base)){
console.log("Specify value for base parameter");
}
if (isEmpty(exp)){
console.log("Specify value for exponent parameter");
}
fillNumSeq(base,exp);
var emax;
var eseq;
var nseed;
var nspan;
emax = (numSeq.length);
eseq = Math.floor(Math.random()*emax)+1;
nseed = numSeq[eseq].num;
nspan = Math.floor((Math.random())*(Math.random()*nseed))+1;
return Math.floor(Math.random()*nspan)+1;
}
console.log(getRandNum(10,20),numSeq);
//testing:
//getRandNum(-10,20);
//console.log(getRandNum(-10,20),numSeq);
//console.log(numSeq);
loop { begin Bar.new rescue SystemExit p $! #: #<SystemExit: exit> end }
This will print #<SystemExit: exit>
in an infinite loop, without ever exiting.

There's also Array.find()
in ES6 which returns the first matching element it finds.
https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/find
const myArray = [1, 2, 3]
const myElement = myArray.find((element) => element === 2)
console.log(myElement)
// => 2
If someone is still looking for an answer, for me the problem was in routes/web.php file. Example:
Route::get('/', function () {
return view('welcome');
});
It is also Route, so yeah...Just remove it if not needed and you are good to go! You should also follow answers provided from above.
You can use the Test-Path
cmd-let. So something like...
if(!(Test-Path [oldLocation]) -and !(Test-Path [newLocation]))
{
Write-Host "$file doesn't exist in both locations."
}
Just one line of coding is enough.. just try this out. and you can adjust even thicknes of icon-bar with this by adding pixels.
HTML
<div class="navbar-header">
<button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#defaultNavbar1" aria-expanded="false"><span class="sr-only">Toggle navigation</span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</button>
<a class="navbar-brand" href="#" <span class="icon-bar"></span><img class="img-responsive brand" src="img/brand.png">
</a></div>
CSS
.navbar-toggle, .icon-bar {
border:1px solid orange;
}
BOOM...
While I agree that it's better to use the built-in foreach
construct in most cases, I find the use of this variation on the ForEach<> extension to be a little nicer than having to manage the index in a regular foreach
myself:
public static int ForEach<T>(this IEnumerable<T> list, Action<int, T> action)
{
if (action == null) throw new ArgumentNullException("action");
var index = 0;
foreach (var elem in list)
action(index++, elem);
return index;
}
Example
var people = new[] { "Moe", "Curly", "Larry" };
people.ForEach((i, p) => Console.WriteLine("Person #{0} is {1}", i, p));
Would give you:
Person #0 is Moe
Person #1 is Curly
Person #2 is Larry
Add the disable part in the submit event.
$(document).ready(function () {
$("#yourFormId").submit(function () {
$(".submitBtn").attr("disabled", true);
return true;
});
});
If you want to modify the original array instead of returning a new array, use .push()
...
array1.push.apply(array1, array2);
array1.push.apply(array1, array3);
I used .apply
to push the individual members of arrays 2
and 3
at once.
or...
array1.push.apply(array1, array2.concat(array3));
To deal with large arrays, you can do this in batches.
for (var n = 0, to_add = array2.concat(array3); n < to_add.length; n+=300) {
array1.push.apply(array1, to_add.slice(n, n+300));
}
If you do this a lot, create a method or function to handle it.
var push_apply = Function.apply.bind([].push);
var slice_call = Function.call.bind([].slice);
Object.defineProperty(Array.prototype, "pushArrayMembers", {
value: function() {
for (var i = 0; i < arguments.length; i++) {
var to_add = arguments[i];
for (var n = 0; n < to_add.length; n+=300) {
push_apply(this, slice_call(to_add, n, n+300));
}
}
}
});
and use it like this:
array1.pushArrayMembers(array2, array3);
var push_apply = Function.apply.bind([].push);_x000D_
var slice_call = Function.call.bind([].slice);_x000D_
_x000D_
Object.defineProperty(Array.prototype, "pushArrayMembers", {_x000D_
value: function() {_x000D_
for (var i = 0; i < arguments.length; i++) {_x000D_
var to_add = arguments[i];_x000D_
for (var n = 0; n < to_add.length; n+=300) {_x000D_
push_apply(this, slice_call(to_add, n, n+300));_x000D_
}_x000D_
}_x000D_
}_x000D_
});_x000D_
_x000D_
var array1 = ['a','b','c'];_x000D_
var array2 = ['d','e','f'];_x000D_
var array3 = ['g','h','i'];_x000D_
_x000D_
array1.pushArrayMembers(array2, array3);_x000D_
_x000D_
document.body.textContent = JSON.stringify(array1, null, 4);

Activity gets paused when a Dialog comes above it so all the recommended solutions are half-solutions. You need to create hooks for dialogs as well.
You can't run this particular piece of code in the interactive interpreter. You'll need to save it into a file first so that you can pass the argument to it like this
$ python hello.py user338690
foo(*ob);
You don't need to cast it because it's the same Object type, you just need to dereference it.

For me I just needed to add the following:
if let popoverController = alertController.popoverPresentationController {
popoverController.barButtonItem = navigationItem.rightBarButtonItem
}
Yes, yes you can.
#y.x {
/* will select element of id="y" that also has class="x" */
}
Similarly:
.x#y {
/* will select elements of class="x" that also have an id="y" */
}
Incidentally this might be useful in some use cases (wherein classes are used to represent some form of event or interaction), but for the most part it's not necessarily that useful, since id
s are unique in the document anyway. But if you're using classes for user-interaction then it can be useful to know.
I had this issue for longer than I would like to admit.
I simply just needed to run VS as an administrator, rookie mistake on my part...
Hope this helps someone <3
The simplest thing to do is, change the default table name assigned for the model. Simply put following code,
protected $table = 'category_posts';
instead of protected $table = 'posts';
then it'll do the trick.
However, if you refer Laravel documentation you'll find the answer. Here what it says,
By convention, the "snake case", plural name of the class(model) will be used as the table name unless another name is explicitly specified
Better to you use artisan command to make model and the migration file at the same time, use the following command,
php artisan make:model Test --migration
This will create a model class and a migration class in your Laravel project. Let's say it created following files,
Test.php
2018_06_22_142912_create_tests_table.php
If you look at the code in those two files you'll see,
2018_06_22_142912_create_tests_table.php files' up function,
public function up()
{
Schema::create('tests', function (Blueprint $table) {
$table->increments('id');
$table->timestamps();
});
}
Here it automatically generated code with the table name of 'tests' which is the plural name of that class which is in Test.php file.
If the above solution does not work for you, try this:
#1.1 Do NOT ignore file pattern in any subdirectory
!*/config.php
#1.2 ...only ignore it in the current directory
/config.php
##########################
# 2.1 Ignore file pattern everywhere
config.php
# 2.2 ...but NOT in the current directory
!/config.php
Your code is working at my end, i have just tested it. Where are you checking your changes? Use Documents directory path. To get path -
NSLog(@"%@",documentsDirectory);
and copy path from console and then open finder and press Cmd+shift+g and paste path here and then open your file
Yes, a table have one or many foreign keys and each foreign keys hava a different parent table.
This can also happen if you've recently upgraded Ant. I was using Ant 1.8.4 on a project, and upgraded Ant to 1.9.4, and started to get this error when building a fat jar using Ant.
The solution for me was to downgrade back to Ant 1.8.4 for the command line and Eclipse using the process detailed here
On changing the values of the source data, chart was not getting updated accordingly. Just closed all instances of excel and restarted, problem disappeared.
The simplest way to get tooltips in most browsers is to set some text in the title attribute.
eg.
<img src="myimage.jpg" alt="a cat" title="My cat sat on a table" />
produces (hover your mouse over the image):
a cat http://www.imagechicken.com/uploads/1275939952008633500.jpg
Title attributes can be applied to most HTML elements.
Be careful, if you need precision higher than milliseconds!
.NET (v4.6) methods (e.g. FromUnixTimeMilliseconds) don't provide this precision.
AddSeconds and AddMilliseconds also cut off the microseconds in the double.
These versions have high precision:

On Linux, this is likely to be a limit on the number of file watches.
The development server uses inotify to implement hot-reloading. The inotify API allows the development server to watch files and be notified when they change.
The default inotify file watch limit varies from distribution to distribution (8192 on Fedora). The needs of the development server often exceeds this limit.
The best approach is to try increasing the file watch limit temporarily, then making that a permanent configuration change if you're happy with it. Note, though, that this changes your entire system's configuration, not just node.
To view your current limit:
sysctl fs.inotify.max_user_watches
To temporarily set a new limit:
# this limit will revert after reset
sudo sysctl fs.inotify.max_user_watches=524288
sudo sysctl -p
# now restart the server and see if it works
To set a permanent limit:
echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf
sudo sysctl -p
This is working Oracle example but it should work in MySQL too.
You are missing smth - see IN after END Replace 'IN' with '=' sign for a single value.
SELECT empno, ename, job
FROM scott.emp
WHERE (CASE WHEN job = 'MANAGER' THEN '1'
WHEN job = 'CLERK' THEN '2'
ELSE '0' END) IN (1, 2)
TextBoxFor: It will render like text input html element corresponding to specified expression. In simple word it will always render like an input textbox irrespective datatype of the property which is getting bind with the control.
EditorFor: This control is bit smart. It renders HTML markup based on the datatype of the property. E.g. suppose there is a boolean property in model. To render this property in the view as a checkbox either we can use CheckBoxFor or EditorFor. Both will be generate the same markup.
What is the advantage of using EditorFor?
As we know, depending on the datatype of the property it generates the html markup. So suppose tomorrow if we change the datatype of property in the model, no need to change anything in the view. EditorFor control will change the html markup automatically.
Simple one, just do like this..
ListViewItem lvi = new ListViewItem(pet.Name);
lvi.SubItems.Add(pet.Type);
lvi.SubItems.Add(pet.Age);
listView.Items.Add(lvi);
I wrote this function below where you can change the name of a current key name to a new one.
def change_dictionary_key_name(dict_object, old_name, new_name):
'''
[PARAMETERS]:
dict_object (dict): The object of the dictionary to perform the change
old_name (string): The original name of the key to be changed
new_name (string): The new name of the key
[RETURNS]:
final_obj: The dictionary with the updated key names
Take the dictionary and convert its keys to a list.
Update the list with the new value and then convert the list of the new keys to
a new dictionary
'''
keys_list = list(dict_object.keys())
for i in range(len(keys_list)):
if (keys_list[i] == old_name):
keys_list[i] = new_name
final_obj = dict(zip(keys_list, list(dict_object.values())))
return final_obj
Assuming a JSON you can call it and rename it by the following line:
data = json.load(json_file)
for item in data:
item = change_dictionary_key_name(item, old_key_name, new_key_name)
Conversion from list to dictionary keys has been found here:

I faced this same problem, and I came up with a solution that didn't invole using the ProgressDialog and I get faster results.
What I did was create a layout that has a ProgressBar in it.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<ProgressBar
android:id="@+id/progressImage"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
/>
</RelativeLayout>
Then in the onCreate method do the following
public void onCreate(Bundle icicle) {
super.onCreate(icicle);
setContentView(R.layout.progress);
}
Then do the long task in a thread, and when that's finished have a Runnable set the content view to the real layout you want to use for this activity.
For example:
mHandler.post(new Runnable(){
public void run() {
setContentView(R.layout.my_layout);
}
});
This is what I did, and I've found that it runs faster than showing the ProgressDialog and it's less intrusive and has a better look in my opinion.
However, if you're wanting to use the ProgressDialog, then this answer isn't for you.
Instead of ng-options="product as product.label for product in products">
in the select element, you can even use this:
<option ng-repeat="product in products" value="{{product.label}}">{{product.label}}
which works just fine as well.
Function pointer is usually defined by typedef
, and used as param & return value.
Above answers already explained a lot, I just give a full example:
#include <stdio.h>
#define NUM_A 1
#define NUM_B 2
// define a function pointer type
typedef int (*two_num_operation)(int, int);
// an actual standalone function
static int sum(int a, int b) {
return a + b;
}
// use function pointer as param,
static int sum_via_pointer(int a, int b, two_num_operation funp) {
return (*funp)(a, b);
}
// use function pointer as return value,
static two_num_operation get_sum_fun() {
return ∑
}
// test - use function pointer as variable,
void test_pointer_as_variable() {
// create a pointer to function,
two_num_operation sum_p = ∑
// call function via pointer
printf("pointer as variable:\t %d + %d = %d\n", NUM_A, NUM_B, (*sum_p)(NUM_A, NUM_B));
}
// test - use function pointer as param,
void test_pointer_as_param() {
printf("pointer as param:\t %d + %d = %d\n", NUM_A, NUM_B, sum_via_pointer(NUM_A, NUM_B, &sum));
}
// test - use function pointer as return value,
void test_pointer_as_return_value() {
printf("pointer as return value:\t %d + %d = %d\n", NUM_A, NUM_B, (*get_sum_fun())(NUM_A, NUM_B));
}
int main() {
test_pointer_as_variable();
test_pointer_as_param();
test_pointer_as_return_value();
return 0;
}
Simple and quick:
Dim lastRow as long
Range("A1").select
lastRow = Cells.Find("*",SearchOrder:=xlByRows,SearchDirection:=xlPrevious).Row
Example use:
cells(lastRow,1)="Ultima Linha, Last Row. Youpi!!!!"
'or
Range("A" & lastRow).Value = "FIM, THE END"
Use overrideLibrary
when the minSdk is declared in build.gradle
instead of in AndroidManifest.xml
If you are using Android Studio:
add <uses-sdk tools:overrideLibrary="android.support.v17.leanback"/>
to your manifest, don't forget to include xmlns:tools="http://schemas.android.com/tools"
too.
You should call the events after the document is ready, like this:
$(document).ready(function () {
// Your code
});
This is because you are trying to manipulate elements before they are rendered by the browser.
So, in the case you posted it should look something like this
$(document).ready(function () {
var editorTitle = $('#editorTitle').val();
var editorText = $('#editorText').html();
});
Hope it helps.
Tips: always save your jQuery object in a variable for later use and only code that really need to run after the document have loaded should go inside the ready() function.
you have just introduce parameter startDate as mentioned below.
var todaydate = new Date();
$(".leave-day").datepicker({
autoclose: true,
todayBtn: "linked",
todayHighlight: true,
startDate: todaydate
}
).on('changeDate', function (e) {
var dateCalendar = e.format();
dateCalendar = moment(dateCalendar, 'MM/DD/YYYY').format('YYYY-MM-DD');
$("#date-leave").val(dateCalendar);
});
The GitHub repository setup page is just a suggested list of commands (and GitHub now suggests using the HTTPS protocol). Unless you have administrative access to GitHub's site, I don't know of any way to change their suggested commands.
If you'd rather use the SSH protocol, simply add a remote branch like so (i.e. use this command in place of GitHub's suggested command). To modify an existing branch, see the next section.
$ git remote add origin [email protected]:nikhilbhardwaj/abc.git
As you already know, to switch a pre-existing repository to use SSH instead of HTTPS, you can change the remote url within your .git/config
file.
[remote "origin"]
fetch = +refs/heads/*:refs/remotes/origin/*
-url = https://github.com/nikhilbhardwaj/abc.git
+url = [email protected]:nikhilbhardwaj/abc.git
A shortcut is to use the set-url
command:
$ git remote set-url origin [email protected]:nikhilbhardwaj/abc.git
In the hopes of providing additional information for those who don't pick this up as quickly as others, I'd like to provide my scenario as it has a slightly different setup. My project was setup with the following directory structure (using Eclipse):
Project/ src/ // application source code org/ myproject/ MyClass.java test/ // unit tests res/ // resources images/ // PNG images for icons my-image.png xml/ // XSD files for validating XML files with JAXB my-schema.xsd conf/ // default .conf file for Log4j log4j.conf lib/ // libraries added to build-path via project settings
I was having issues loading my resources from the res directory. I wanted all my resources separate from my source code (simply for managment/organization purposes). So, what I had to do was add the res directory to the build-path and then access the resource via:
static final ClassLoader loader = MyClass.class.getClassLoader();
// in some function
loader.getResource("images/my-image.png");
loader.getResource("xml/my-schema.xsd");
loader.getResource("conf/log4j.conf");
NOTE: The /
is omitted from the beginning of the resource string because I am using ClassLoader.getResource(String) instead of Class.getResource(String).
If your SDK tools directory is missing, maybe you deleted it by accident and there is a easy way to download it and guide android studio to it.
First go to android developer site (https://developer.android.com/studio/index.html), scroll to the bottom of the page and chose your download according to system you have(but don't download installer version for windows) you need a zip file which contains SDK.
After you download just put it in my documents (MAC or WINDOWS) and then when you open android studio screen will popup for installing SDK (like the time that you got error), don't click next, go to browse, find that file and press ok. After that go next and it will work like a charm.
That's it.
Link with -static. When you link with -static the linker embeds the library inside the executable, so the executable will be bigger, but it can be executed on a system with an older version of glibc because the program will use it's own library instead of that of the system.

I changed the output path of the service. it should be inside bin
folder of the service project. Once I put the output path back to bin
, it worked.
This happened to me because I put a variable in the regex and sometimes its string value included a slash. Solution: preg_quote.
this code probable help you .
<iframe src="" onload="this.width=screen.width;this.height=screen.height;">
Kindly ensure, the other columns are not constrained to accept Not null
values, hence while creating columns in table just ignore "Not Null" syntax. eg
Create Table Table_Name(
col1 DataType,
col2 DataType);
You can then insert multiple row values in any of the columns you want to. For instance:
Insert Into TableName(columnname)
values
(x),
(y),
(z);
and so on…
Hope this helps.
Don't know others issue, Only this code worked for me.

I'm surprised noone's voted up Shao's answer that, as I understand it, it is impossible to do what's asked in standard C99, since converting a pointer to an integral type formally is undefined behavior. (Apart from the standard allowing conversion of uintptr_t
<-> void*
, but the standard does not seem to allow doing any manipulations of the uintptr_t
value and then converting it back.)
Yes. The answer is yes.

Logit is a function that maps probabilities [0, 1]
to [-inf, +inf]
.
Softmax is a function that maps [-inf, +inf]
to [0, 1]
similar as Sigmoid. But Softmax also normalizes the sum of the values(output vector) to be 1.
Tensorflow "with logit": It means that you are applying a softmax function to logit numbers to normalize it. The input_vector/logit is not normalized and can scale from [-inf, inf].
This normalization is used for multiclass classification problems. And for multilabel classification problems sigmoid normalization is used i.e. tf.nn.sigmoid_cross_entropy_with_logits
the third example of the accepted answer give an erroneous answer and does not attempt to give duplicates. Here is the correct version :
number_lst = [1, 1, 2, 3, 5, ...]

duplicate_set = set(x for x in number_lst if x in seen_set or seen_set.add(x))
unique_set = seen_set - duplicate_set

arr(x, y) = arr(x, y) & " & "" " & append & """"

The best HTTP header for your client to send an access token (JWT or any other token) is the Authorization
header with the Bearer
authentication scheme.
This scheme is described by the RFC6750.
Example:
GET /resource HTTP/1.1
Host: server.example.com
Authorization: Bearer eyJhbGciOiJIUzI1NiIXVCJ9TJV...r7E20RMHrHDcEfxjoYZgeFONFh7HgQ
If you need stronger security protection, you may also consider the following IETF draft: https://tools.ietf.org/html/draft-ietf-oauth-pop-architecture. This draft seems to be a good alternative to the (abandoned?) https://tools.ietf.org/html/draft-ietf-oauth-v2-http-mac.
Note that even if this RFC and the above specifications are related to the OAuth2 Framework protocol, they can be used in any other contexts that require a token exchange between a client and a server.
Unlike the custom JWT
scheme you mention in your question, the Bearer
one is registered at the IANA.
Concerning the Basic
and Digest
authentication schemes, they are dedicated to authentication using a username and a secret (see RFC7616 and RFC7617) so not applicable in that context.
Hi try this it will create directory + file inside it

try {
File img = new File("somefile.png");
BufferedImage image = ImageIO.read(img );
System.out.println(image);
} catch (IOException e) {

Each button press results in an elevator request which has to be served. Each of these requests is tracked at a global place
The number of elevators in the building will be determined by the user. The building will contain a fixed number of floors. The number of passengers that can fit into the elevator will be fixed. The passengers will be counted as they leave the elevator at their destination floor. The destination floor will be determined using a "random" Poisson interval. When all of the passengers in the elevator have reached their destination floors, the elevator will return to the lobby to pickup more passengers
Are you sure that you want "055" as opposed to "55"? Some programs interpret a leading zero as meaning octal, so that it would read 055 as (decimal) 45 instead of (decimal) 55.
That should just mean dropping the '0' (zero-fill) flag.
e.g., change System.out.printf("%03d ", x);
to the simpler System.out.printf("%3d ", x);
In the text box that contains the header, you can use an expression to get the date. Try something like
="Report Generation Date: " & Today()
right click in the text box in the layout view. At the bottom of the list you'll see the expression option. There you will be able to enter the code. This option will allow you to avoid adding a second textbox.

Today, there are JS libraries for you, if you don't want to get into the nitty gritty of the different methods described on this page.
On of these is https://github.com/hubspot/offline. It checks for the connectivity of a pre-defined URI, by default your favicon. It automatically detects when the user's connectivity has been reestablished and provides neat events like up
and down
, which you can bind to in order to update your UI.
No, it is not considered good practice. On the contrary, it is generally considered a bad idea.
http://www.gotw.ca/publications/mill22.htm goes into a lot more detail about why, but the problem is partly that the compiler is unable to enforce this, so it has to be checked at runtime, which is usually undesirable. And it is not well supported in any case. (MSVC ignores exception specifications, except throw(), which it interprets as a guarantee that no exception will be thrown.
All the answers talk about horizontal align.
For vertical aligning multiple content elements, take a look at this approach:
<div style="display: flex; align-items: center; width: 200px; height: 140px; padding: 10px 40px; border: solid 1px black;">_x000D_
<div>_x000D_
<p>Paragraph #1</p>_x000D_
<p>Paragraph #2</p>_x000D_
</div>_x000D_
</div>
_x000D_
you could write an extension method
public static void Fill<T>(this T[] array, T value)
{
for(int i = 0; i < array.Length; i++)
{
array[i] = value;
}
}
Assuming you already have the blank database created, you can also restore a database from the command line like this:

If you are using the PowerShell Community Extensions there is a Get-Hash commandlet that will do this easily:
C:\PS> "hello world" | Get-Hash -Algorithm MD5
Algorithm: MD5
Path :
HashString : E42B054623B3799CB71F0883900F2764
If there is space between the letters of the font, you need to use quote.
font-family:"Calibri (Body)";
You can use 2 ways: int? or Nullable, both have the same behavior. You could to make a mix without problems but is better choice one to make code cleanest.
Option 1 (With ?):
private void Example(int? arg1, int? arg2)
{
if (arg1.HasValue)
{
//do something
}
if (arg1.HasValue)
{
//do something else
}
}
Option 2 (With Nullable):
private void Example(Nullable<int> arg1, Nullable<int> arg2)
{
if (arg1.HasValue)
{
//do something
}
if (arg1.HasValue)
{
//do something else
}
}
From C#4.0 comes a new way to do the same with more flexibility, in this case the framework offers optional parameters with default values, of this way you can set a default value if the method is called without all parameters.
Option 3 (With default values)
private void Example(int arg1 = 0, int arg2 = 1)
{
//do something else
}
A RESTful resource controller sets up some default routes for you and even names them.
Route::resource('users', 'UsersController');
Gives you these named routes:
Verb Path Action Route Name
GET /users index users.index
GET /users/create create users.create
POST /users store users.store
GET /users/{user} show users.show
GET /users/{user}/edit edit users.edit
PUT|PATCH /users/{user} update users.update
DELETE /users/{user} destroy users.destroy
And you would set up your controller something like this (actions = methods)
class UsersController extends BaseController {
public function index() {}
public function show($id) {}
public function store() {}
}
You can also choose what actions are included or excluded like this:
Route::resource('users', 'UsersController', [
'only' => ['index', 'show']
]);
Route::resource('monkeys', 'MonkeysController', [
'except' => ['edit', 'create']
]);
Laravel 5.5 added another method for dealing with routes for resource controllers. API Resource Controller acts exactly like shown above, but does not register create
and edit
routes. It is meant to be used for ease of mapping routes used in RESTful APIs - where you typically do not have any kind of data located in create
nor edit
methods.
Route::apiResource('users', 'UsersController');
RESTful Resource Controller documentation
An Implicit controller is more flexible. You get routed to your controller methods based on the HTTP request type and name. However, you don't have route names defined for you and it will catch all subfolders for the same route.
Route::controller('users', 'UserController');
Would lead you to set up the controller with a sort of RESTful naming scheme:
class UserController extends BaseController {
public function getIndex()
{
// GET request to index
}
public function getShow($id)
{
// get request to 'users/show/{id}'
}
public function postStore()
{
// POST request to 'users/store'
}
}
Implicit Controller documentation
It is good practice to use what you need, as per your preference. I personally don't like the Implicit controllers, because they can be messy, don't provide names and can be confusing when using php artisan routes
. I typically use RESTful Resource controllers in combination with explicit routes.
Updated Answer
* Updated answer which support the v2.1.1** bootstrap version stylesheet.
**But be careful because this solution has been removed from v3
Just wanted to point out that this solution is not needed anymore as the latest bootstrap now supports multi-level dropdowns by default. You can still use it if you're on older versions but for those who updated to the latest (v2.1.1 at the time of writing) it is not needed anymore. Here is a fiddle with the updated default multi-level dropdown straight from the documentation:

Original Answer
There have been some issues raised on submenu support over at github and they are usually closed by the bootstrap developers, such as this one, so i think it is left to the developers using the bootstrap to work something out. Here is a demo i put together showing you how you can hack together a working sub-menu.
Relevant code
CSS
.dropdown-menu .sub-menu {
left: 100%;
position: absolute;
top: 0;
visibility: hidden;
margin-top: -1px;
}
.dropdown-menu li:hover .sub-menu {
visibility: visible;
display: block;
}
.navbar .sub-menu:before {
border-bottom: 7px solid transparent;
border-left: none;
border-right: 7px solid rgba(0, 0, 0, 0.2);
border-top: 7px solid transparent;
left: -7px;
top: 10px;
}
.navbar .sub-menu:after {
border-top: 6px solid transparent;
border-left: none;
border-right: 6px solid #fff;
border-bottom: 6px solid transparent;
left: 10px;
top: 11px;
left: -6px;
}
Created my own .sub-menu
class to apply to the 2-level drop down menus, this way we can position them next to our menu items. Also modified the arrow to display it on the left of the submenu group.
